sIGNORs To THE BEANS SPRING COMPANY, on MAssILLoN, OIIIO, A CORPORATION OF OHIO.

Application filed. November To ZZ whom 'it may concer/n:

Be it known that we, JOHN F. BEANS and 'ALONZO J'. Mnnclnn, both citizens of the United States, residing at Canton, Stark County, Ohio, and Massillon, Stark County, Ohio, respectively, have invented a new and usel'ul `Machine for 'Bending Bumper lrrackets, ot which the 'following is a specification.

' rlhis invention relates to a bending Vmachine and more particularlyto a device `for bending a` bracket especially designed :tor supporting an automobile bumper upon the aiiltomobile.

rlhe objects of the invention are to provide a machine of this character in which a bracket may be easily and quickly formed, in two continuous operations, from a straight bar of spring steel or the like.

rlhe above and other objects may be at tained by providing a bending die around which the bar ot' steel is bent by a roller upon a swinging arm, a ren'iovable block being provided for engagement with the partially completed product, a secondfroller upon a swinging arm being provided for bending the end portion of the bracket back upon the removable block to complete the bracket.

A practical embodiment of the invention thus set forth in general terms is illustrated in the aceoi'npanying drawings, in which- Figure 1 is a plan view of the machine showing a bar in the initial position;

Fig. 2, a similar view showing the first beiufling ope 'ation ofthe bar;

Fi 3, a similar view showing the second bending operation;

Fig. 4, an edge elevation of the table and be n di n g die Fig. 5, a side View ot' one ot the swinging arms and rollers; and p Fig. 6, a perspective view Oi one of the finished brackets.

Similar numerals et reference indicate `corresponding parts throughout the drawings.

1`he machine includes a table 1 upon which is fixed a block 2V having the straight edge 3, and the curved edge 4 continuous therewith and terminating at the cut-out portion 5. One or more pins 6 are spaced from the straight edge 3 of the block to accommodate brackets of different sizes.

The blank A. from which each bracket is MACHINE FOR BENDING BUMPER BBACKETS.

vided with an elongated slot 12 in which l the squared portion 13 of a journal 14 is arranged` to be. adjusted as by the nut 15 upon the threaded end 1G thereof, said ournal having a head 17 to prevent Vdisplacen ment of the roller 18 which is journaled thereon.

This arm is placed in the position shown in full lines in FiO. 1 and then swung around upon its pivot, the roller carrying the free end of the bar around the curved edge tot the block, assuming irst the position shown at B in Fig. 1, and finally the position shown in Fig. 2, the tree end of the bar A being extended past the cut-out portion 5 oit the block.

The arm 8 is then removed and an arm 19V similar to the arm V8 having a roller 2O mounted closer to the pivotalipoint, is then brought into use, the journal portion of said arm being insert-ed into a bearing opening 21 in the table, the arm and roller first assuming the positions shown at C in dot and'dash lines, the roller engaging the tree end portion of the bar indicated at D in Fig. 8.

A removable bending block 21 is then inserted, as shown in Fig. 3, the curved edge 22 thereotl engaging the curved portion ot the bar, the end of said. removable block engaging the `journal portion 24 oi the varm 19.

The y arm 19 is then swung downward bending the free end of the bar to the position shown at E in Fig. 3 and cont-inuing around into the position shown in full. lines in said figure, 'forming the finished bracket as shown in Fig. 6, having the hooked upper end 7 the depending straight portion- 25, the lower curved portion' '26 and the downturned end 27.

The openings 28 may be punched in the blank before the saine is placed in the bending machine, these 'openings forming :no

part of the present invention, but being necessary in the finished bracket in order to connect the bumper, Which is shown in a co-pending application.

It will thus be seen that with two easy and simple operations which are readily accomplished, the blank bar, after being properly heated, may be quickly' and easily formed around thestationary block and a removable block by means of the two pivoted arms, the rollers upon which press the bar around the bending blocks fas above described.

te claim 1. A bending machine including a table, a iixed bending block thereon having a straight edge terminating in a curved edge, a swinging arm arranged to be pivotally connected to the block and provided with a roller for bending the bar around the curved edge of the block, the table lhaving a bearing aperture at the extremity of said curved edge of the block, a detachable arm having a journal portion `adapted to be engaged in said bearing aperture, a removable `block adapted to bear against said journal portion, and a roller upon said detachable arm Vfor bending the free extremity of the bar back upon the removable block.

2. A bending machine for bending a bar provided With a hooked end and comprising a table, a fixed bending block thereon having a straight edge terminating in a curved edge, a pin in the t-able near the end of the straight portion of the block for engagement with the hooked end of the bar, a swinging arm arranged to be pivotally connected to the block and provided With a roller for bending the bar around the curved edge of the block, the table having a bearing aperture at the extremity of the curved portion of the block, a detachable arm having a ljournal portion adapted to be engaged in said bearing aperture, a removable block adapted to bear against said journal portion, and a roller upon said detachable arm for bending the free extremity of the bar back upon the removable block.
